IO performance regressions with kernel-2.6.32-358

[Orion Poplawski]

Is anyone else seeing IO performance regressions with kernel-2.6.32-358? 
 We have a SL6.3 machine that serves a dual purpose of VM host and runs 
our amanda backups to local disk.  Since booting kernel-2.6.32-358 our 
backups are taking significantly longer (and estimates are timing out). 
 Have not yet had the chance to boot back to an earlier kernel.  Since 
it also hosts some VMs (although they tend to be lightly loaded) it 
might more related to that.
